i just recently have a problem that came upon my 73 type 1 bug. i think it is my router and pins. becasue of it back fireing all the time. also it does not want to go above 30 mph. my friend seems to think it is the destrubitor. i need help

 

What is router and pins? Are you saying rotor and points,
located inside the distributor? The old bug was bad about
wearing down the points rubbing block that rubs against
the 4 lobe cam, The points gap would close up and cause
a problem some what like you suggesting.
